Chương 22: Chapter 21: Structure

The new laboratory looked better at night. In daylight, even the little that reached the cellar through the loading hatch found things to criticise: damp at the base of the alley doors, smoke worked deep into the mortar, a pump that shrieked every time Kellan used it, and a crack running down one of the square support pillars. Elizabeth stood beneath the crack long enough that Kellan eventually looked up from the ledger.

"If you stare at it any harder, it may collapse out of spite."

"I'm deciding whether it's superficial."

"You're eleven and not a mason."

"I'm aware."

"Good. Because I paid one to check the main arch before we bought the place. I didn't pay him to bless every stone in the cellar." Elizabeth gave the pillar one last look and unfolded the list she had brought. She had already divided the work by urgency: what had to exist before research could begin, what could wait a few weeks, and what she wanted but did not yet need. Kellan took the page from her.

"Heat, light, dry storage, benches, cabinets, drainage repair. Another bar on the loading hatch." He glanced towards the doors.

"Already done." Elizabeth followed his gaze. A fresh iron bracket crossed the inside of the hatch, inconveniently high for her but thick enough to matter.

"You didn't mention buying it."

"Eight silver. Your rule was to tell you before I spent more than a crown on anything that wasn't listed." He had obeyed the wording exactly. Elizabeth was beginning to suspect he enjoyed that more than open defiance. Kellan turned the sheet over.

"This is the wrong way to buy most of it."

"How?"

"You're thinking like Crownspire. Five respectable shops, five neat purchases, five people wondering why the same man wants clamps, glass, coal, leather, acids and storage jars in the same week." He tapped the paper with one finger.

"A salvage broker near the canal can sell me half of this from factory clear-outs and failed workshops, and he'll care a lot more about the coin than what I'm building."

"One seller sees the whole pattern."

"Only if he bothers looking. Most don't." That was plausible, and more importantly it was the kind of judgement Elizabeth couldn't make from inside the academy. She let him cross out two suppliers, replace another with the salvage broker, and add hired labour at the bottom. She frowned at that last addition. Kellan pointed towards the stairs.

"You planning to carry a cast-iron stove down here yourself?" Elizabeth looked at the narrow stairwell, then back at the page.

"Leave it."

"How generous."

"How much money do you have left?"

"Enough for repairs and some equipment. Not enough for everything you've written."

"I can bring more."

"I know you can." He handed the list back.

"Still worth deciding where it goes before you spend it." Elizabeth disliked being told to budget with her father's allowance sitting in a strongbox at Crownspire, but Kellan had already saved more than his lodging cost by arguing over the chandlery. She gave him a ceiling for the week, kept the rest of the money with her, and left the cellar in his hands. At Crownspire, Light was waiting. Crude Light had improved enough that it no longer felt fragile.

Elizabeth could form it without several seconds of concentration, move her hand without the glow shivering apart, and hold it for longer before the mana cost became irritating. The problem was that it still wasted energy. Ensure your favorite authors get the support they deserve. Read this novel on Royal Road. Ruby, who had spent the last ten minutes adjusting a prism between two clamps, seemed offended on the skill's behalf.

"You built a functioning Light skill in a few weeks and you're sulking because it gets warm."

"I'm not sulking."

"You have a scientific version of sulking. It involves staring at thermometers." Elizabeth activated Crude Light over her palm. The glow settled into the familiar pale sphere, brighter at the centre than the edges. Ruby slid a treated alloy strip beneath it, waited, then pulled the strip back when a faint darkening appeared along one side.

"There," Ruby said.

"Again." Elizabeth repeated the trial at a higher mana input. The light strengthened, but so did the heat gathering against her skin. Increasing the input was giving her less useful illumination for each additional unit of mana. Ruby leaned over the notes.

"You keep changing the shell."

"The boundary controls the conversion region."

"Maybe. Or maybe you decided it does because that's how you built the first version." Elizabeth looked at her. Ruby raised both hands.

"I'm just saying the edge might not be the important part." That was irritating enough to be useful. Elizabeth dismissed the glow and watched Ruby produce her own. Ruby's mana did not seem to fill a fixed shape and sit there. The pattern renewed itself continuously, motion passing through the structure too quickly to notice without looking for it. Elizabeth rebuilt Crude Light with that in mind. Instead of supplying the entire conversion region at once, she pushed mana through it in sequence.

The first attempt faded before the cycle completed. On the second, the returning pattern met the next wave badly and the whole structure flashed blue-white before collapsing. Ruby jerked her head back.

"That one felt personal."

"The timing is wrong."

"Your loop's catching itself." Elizabeth opened Process Mapping and watched the failure again in memory. Ruby was right. The cycle returned to the starting region before the next section had finished changing state, forcing two incompatible phases into the same space. She lengthened the interval. This time the light remained. Ruby checked the thermometer, frowned, then checked it again.

"That's barely moved." Elizabeth changed the cycle rate without increasing the mana supply. The colour shifted towards blue. Slowing it pulled the light back through white and into a warmer gold, while brightness changed far less than she expected.

"Do that again," Ruby said. Elizabeth did, then rebuilt the structure once more. She stopped treating it as several conversion regions joined inside a container and made the entire thing one repeating lattice, the same state travelling through it in order. There was less for the mana to fight because the competing sections were gone. White light formed above her palm. It was steadier than anything Crude Light had produced before. When Elizabeth moved her wrist, the structure bent with her rather than tearing apart.

She compressed it into an oval, then a narrow bar, and changed the internal rate until the white cooled into pale blue. The System appeared. Crude Light has reached Level 10. Evolution available. Elizabeth accepted before Ruby could ask what she was seeing. Structured Light — Level 1 Creates controlled visible illumination within a stable repeating mana lattice. Output characteristics may be adjusted by altering the structure and internal pattern. Continuous mana supply required.

The bar of light remained above her hand, almost perfectly still. Ruby stared at it.

"You're smiling."

"I know."

"That's unnerving." Elizabeth shifted the light to gold, then back to blue. Ruby's expression broke into a grin.

"All right. That's actually good." They spent the rest of the session finding out how far the new structure could be pushed before it became unstable. Simple shapes held. Distance increased the cost quickly. More elaborate forms failed once the lattice had too much geometry to maintain, but the old thermal waste had dropped sharply. What interested Elizabeth most was the motion inside it. The lattice did more than contain the effect; it organised it.

That suggested a different way to think about Kellan's Lightning Needle. Perhaps the structure around the charge was not merely a shell either. The thought stayed with her until the following evening, when she returned to the chandlery and found the larger cellar marked with chalk. Kellan had divided the floor into rough working areas. Storage had been pushed towards the stairs, the worst shelving removed, and the loading hatch now sat behind fresh seals. A second-hand stove waited in one corner.

Along the far wall, he had cleared a strip of floor and moved the remaining metal shelving behind it rather than beside it. Elizabeth looked over the arrangement.

"You made a test area."

"I made somewhere you can throw lightning without hitting every metal object in the room."

"You didn't know I was testing Lightning Needle next."

"I knew lightning was involved eventually. Felt like a safe guess." It was better than the arrangement she had pictured. Elizabeth set her bag on the nearest bench and opened the ledger. Receipts had been fixed beside each expense, with several purchases crossed out and replaced by cheaper equivalents.

"Leave the layout," she said. Kellan's eyebrows lifted.

"No argument?"

"Would you prefer one?"

"No. I'm enjoying the novelty." Elizabeth closed the ledger.

"I need to see Lightning Needle again." His amusement thinned. She noticed.

"Not tonight." Kellan looked around at the cellar, as if checking whether he had heard correctly.

"The pump still needs work," Elizabeth continued.

"We need dry storage before reagents come in, and I want the stove checked before anyone lights it. We do those first." He studied her for another moment, then nodded towards the cleared strip.

"And when all that's done?" Elizabeth thought of the moving lattice that had turned Crude Light into something controlled.

"Then we find out what your skill is actually holding together."
